Nova boot fails when freed SRIOV port is used for booting
Status in Nova:

Bug description:
Nova boot fails when freed SRIOV port is used for booting
steps to reproduce:
==================
1.create a SRIOV port
2.boot a vm -->Boot is successful and vm gets ip
3.now delete the vm using nova delete --successful (mac is released from VF)
4.using the port created in step 1 boot a new vm.
VM fails to boot with following error

Expected :
=========
As port is unbound in step 3 we should be able to bind it in step 4.
The setup consists of controller and compute node with Mellanox card
enabled for SRIOV. Ubuntu 14.04 qcow2 image is used for tenant VM boot
Tested the above with MItaka code.
